写一段飞机大战python代码

好的，下面给您提供一段简单的飞机大战游戏的 Python 代码，供参考：

import pygame
import random

# 初始化游戏
pygame.init()

# 设置游戏屏幕大小
screen_width, screen_height = 600, 800
screen = pygame.display.set_mode((screen_width, screen_height))

# 加载游戏素材图片
background = pygame.image.load("bg.jpg")
plane_image = pygame.image.load("plane.png")
enemy_plane_image = pygame.image.load("enemy.png")
bullet_image = pygame.image.load("bullet.png")

# 设置游戏基础变量
score = 0
bullet_speed = 10
enemy_speed = 2

# 创建飞机类
class Plane(pygame.sprite.Sprite):
    def __init__(self):
        super(Plane, self).__init__()
        self.image = plane_image
        self.rect = self.image.get_rect()
        self.rect.centerx = screen_width // 2
        self.rect.bottom = screen_height - 10
        self.speed = 8
        self.bullets = pygame.sprite.Group()

    def update(self, keys):
        if keys[pygame.K_LEFT] and self.rect.left > 0:
            self.rect.x -= self.speed
        if keys[pygame.K_RIGHT] and self.rect.right < screen_width:
            self.rect.x += self.speed
        if keys[pygame.K_SPACE]:
            self.bullets.add(Bullet(self.rect.centerx, self.rect.top))

# 创建子弹类
class Bullet(pygame.sprite.Sprite):
    def __init__(self, x, y):
        super(Bullet, self).__init__()
        self.image = bullet_image
        self.rect = self.image.get_rect()
        self.rect.centerx = x
        self.rect.bottom = y
        self.speed = bullet_speed

    def update(self):
        self.rect.y -= self.speed
        if self.rect.bottom <= 0:
            self.kill()

# 创建敌机类
class EnemyPlane(pygame.sprite.Sprite):
    def __init__(self):
        super(EnemyPlane, self).__init__()
        self.image = enemy_plane_image
        self.rect = self.image.get_rect()
        self.rect.left = random.randint(0, screen_width - self.rect.width)
        self.rect.bottom = 0
        self.speed = enemy_speed

    def update(self):
        self.rect.y += self.speed
        if self.rect.top >= screen_height:
            self.kill()

# 创建所有精灵组
all_sprites = pygame.sprite.Group()
enemies = pygame.sprite.Group()
bullets = pygame.sprite.Group()

# 创建飞机实例
plane = Plane()

# 将飞机实例添加进精灵组里
all_sprites.add(plane)

# 设置游戏循环
running = True
while running:
    # 处理游戏内部事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # 检测键盘输入
    keys = pygame.key.get_pressed()
    plane.update(keys)

    # 产生敌机
    if random.randint(1, 100) <= 5:
        enemy = EnemyPlane()
        all_sprites.add(enemy)
        enemies.add(enemy)

    # 更新所有精灵位置
    all_sprites.update()

    # 检测子弹是否击中敌机
    hits = pygame.sprite.groupcollide(bullets, enemies, True, True)
    for hit in hits:
        score += 1

    # 清除无用的子弹实例
    for bullet in bullets:
        if bullet.rect.bottom <= 0:
            bullet.kill()

    # 绘制游戏画面
    screen.blit(background, (0, 0))
    all_sprites.draw(screen)

    # 显示游戏得分
    score_text = pygame.font.SysFont(None, 30).render("Score: {}".format(score), True, (255, 255, 255))
    screen.blit(score_text, (10, 10))

    # 更新游戏画面
    pygame.display.flip()

# 退出游戏
pygame.quit()

这是一个简单的飞机大战游戏，主要通过精灵组的创建，利用碰撞检测等实现游戏的逻辑功能，以达到游戏的基本玩法。
